" He mused on this village of his, which had sprung up in this place, amid the stones, like the gnarled undergrowth of the valley. All Artaud's inhabitants were inter-related, all bearing the same surname to such an extent that they used double-barrelled names from the cradle up, to distinguish one from another. At some antecedent date an ancestral Artaud had come like an outcast, to establish himself in this waste land. His family had grown with the savage vitality of the vegetation, drawing nourishment from this stone till it had become a tribe, then the tribe turned to a community, till they could not sort out their cousinage, going back for generations. They inter-married with unblushing promiscuity. "

― Émile Zola , La Faute de l'abbé Mouret (Les Rougon-Macquart, #5)
